Mobile phones are notoriously bad at aiding emergency dispatchers in pinpointing your exact location. To address this, Emergency Location Service (ELS) provides 911 with a more accurate location. Google is now launching this lifesaving technology on Android in the U.S. starting with T-Mobile.

While the FCC is still working on E911 in the US, European carriers are beginning to roll out an equivalent service to send your phone’s location to emergency services when you dial an emergency number. Google announced today that support for this possibly life-saving feature is already built into Android as part of Play Services.
